Lughnasadh, one of the key Celtic festivals, holds a deep connection to the agricultural cycle and symbolizes the first harvest. The festival's name derives from the god Lugh, known in Celtic mythology as the wise and skillful deity of light, crafts, and arts. Traditionally celebrated at the end of July or the beginning of August, Lughnasadh corresponded to the time when grain crops ripened and the season of harvesting cereals began. This festival marked gratitude to the earth for its gifts and expressed hope for a successful outcome of the remaining agricultural season.

Yule, one of the main festivals in the Wheel of the Year, celebrated on the day of the winter solstice, is deeply rooted in Celtic tradition. It symbolizes the end of the darkest period of the year and the rebirth of light. For the Celts, this festival held key significance as it marked the moment when the days begin to gradually lengthen and the forces of light start to overcome darkness.
